To all whom it may concern:

Be it known that we, ALEXANDER WIN- TON and HAROLD B. ANDERSON, citizens of the United States, residing at Cleveland, in the county of Ouyah oga and State of Ohio, haveinvented certain new and useful Improvements in Lubricatin Systems for Autombbiles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to im rovementsin' lubricating systems for automo iles, and pertains to some improvements in that type of lubricating system in which the lubricatingoil is used over and over again by a continuous circulation thereof.

The object of the present improvement is to simplify the construction of the above mentioned type of lubricating systems for automoblies, and to at the same time prevent any accumulation of the lubricating oil in the crank-case, which prevents overlubrication of the cylinders by the splashing of an accumulation of oil in the crank case, and thereby working through the cylinders to the spark-plug, and also preventing the issu ing of disagreeable smoky products of combustion through the exhaust, and as a conseuence, also efiectin a saving in the quantlty of lubricating oi used by preventing its being wasted by burning up 1n the engine cylinder.

- The. accompanying drawing is a new of the present improvement, the positions of. the parts being diagrammatically shown.

Referring now to the drawings, 1 is the bottom of the crank-case of a multiple cylinaft, and 3 a sultable oil-filter. Located at the bottom of the crank case, is an inclined pipe, passage-way or channel 4 which is incommunication with the crank case, as here shown, by means of branch passage-ways 5,

into which the oil from the crank-case flows by gravity. Two oil pumps a and?) are connected together and are operated by an eccentriostra 6 which passes around an eccentric 7 w ich is fastened to the crankshaft 2. The pump a is larger than the ump b for the purpose hereinafter described.

11 practice, the diameter of the pump dis a half-inch and the'diameter of the pump b seven-sixteenths. The two pumps bemg driven by a single element 6 they have a uniform reciprocation, and the pump a being of greater capacity by reason of its larger diameter than the pump 1), the former is capable of pumping more oil than the latter.

This pump a draws the oil from the lower end 0 the inclined passage 4 throu h a pipe 8 and forces it throu ha pipe 9 to t e center of the bottom of the lter 3 into a verticall arranged pipe 10 which is located within t e filter and the oil then-flows through suitable openings 11 in the u per end of the pipe and falls through the 'fil t screening or filtering surfaces by the pump 1) through a pipe 14 and is forced througha 1pe'15 to a suitable distributing head 16.

ommunicating with this distributin head 16 area "suitable number'of distri uting pipes 17, which pipes are respectively corinected to the omts of the engine to be, lu-

bricat'ed there y.- The pi e 17 a is a branch p'pe which leads to a Sig) t-feed 18 located u on the dash-board 19 y means-0f which t e operator or driver can always tellwhether the oil distributing pum is working, since a portion of the oil force by the distributing pump 1) is'carried throughfthis pi e 17 and through thesight feed, from whic it passes through the pipe 20 into the filter. By

ering or screening surfaces'12 and 13 to the bottom of the reser- The oil is drawn from the bottom of this reservoir after it has passed through the means of this arrangement a constant and positive circulation of the oil is insured to the earings of the engine in lar e quantities,

which falls to the bottom of t e crank-case and into the passage 4, from which it is immediatel removedby the pump (1', and car= ried to t e filter, from WlllGh it is removed andagain circulated to. the points to be lubricated.

a For convenience 'in the further description and the claims,'the pump-a will be termed av feed-pum and the pump bfla distributing um .2 'lhis arrangement furthermore enables the distributing pump to be made, of a capacity suificient to feed what m ght be termed a flushing uantity of oil to the bearings, aportion of w ich will run on -the crankshaft and cranks and be splashed sufficiently to insure a proper lubrication of the cyl1n-- ders, and overubrication by splash isprevented by reason of the fact that the feed pump is of vgreater capacity than the d1stributing pump, which absolutely prevents any accumulation of oil in the crank-case, and prevents excessive splash-lubrication by reason of the maintenance of a body of oil in the crank-case. That is to say, am 1e lubrication is insured Without any possibl of excessive lubrication with its undesirable features. Excessive lubrication to the cylinders causes a loss of oil by burning it and exhausting the disagreeable products of combustion through the exhaust-of the engine;

this invention prevents excessive lubrication to the cylinders thereby efiecting an economy and preventing a nuisance, and also prevent ing the working of the oil through the cylinders and onto the spark-plug, causing them to short circuit, and also preventing the sooting of the spark-plugs by reason of the burning in the cylinders of the excessive oil fed thereto.

The present improvement also avoids the use of expensive forced-feed lubricators in which there is a se arate pump for each distributing line, whic mechanisms are delicate and liable to get out of order and fail to prciperly perform their function.

avlng thus described theinvention, what is claimed and desired to be secured by Letters Patent, is
